Lessons through maps and map making
This portfolio is a collection of the skills developed in VIS 2128 taught by Professor Carole Voulgaris. The order of these maps are not chronological, instead, they follow a vein that examines what a city provides in terms of access to where an individual interacts with the digital sphere in a city.
On accessibility in Hong Kong
Map 1
As a context for the subsequent maps regarding accessibility in Hong Kong, this map gives one an idea of the public housing, schools and population density landscape in the city and how they account for the observations in later maps. This map also serves to demonstrate the following skills:
- Displaying multiple vector layers on the same map
- Aggregating point data to a layer of polygons
- Calculating and displaying relationships among point and polygon layers based on distance
Access to transit stops
Map 2
Map 3
These maps demonstrate:
- Calculating and displaying accessibility, based on travel time
Pedestrian access to transit tops (Raster layer)
Map 4
This map demonstrates:
- Displaying raster data on a map
- Calculating and displaying accessibility, based on travel time
Pedestrian access to transit tops (Vector layer)
Map 5
This map demonstrates:
- Converting between raster layers and vector layers
- Calculating and displaying accessibility, based on travel time
On ridership in Cambridge
Map 6
This was the first assignment that introduced map making in R. The skills demonstrated are:
- Aggregating point data to a layer of polygons
Unique to our group, we needed to geo-reference the data set for ridership in R by joining the subway line shapefile to the ridership csv file.
On access to hospitals for persons with a disability in Suffolk County, MA
Map 7
This interactive map demonstrates the following skills:
- Displaying data on an interactive map
On Reykjavik, 1902 and today
Map 8
